"h'e interrupted x annular f stated, the Vout-awayV portions of the flange if 18 are preferably disposed in yalinement lwith thesolid portions of the flange V17,v it

will bey obvious that the solid portions of the two Vflanges may be disposed in vertical alinement without departing from the spirit ofthe invention. The openings between the l flanges`17 and 1S are preferably of thesame 115: ing 20 ofthe bolster 111.V The bolst'errll is diameter.

`andthe alined opening of the bearing block 13 is made ofthe same diameter asthe openalso provided with a pocket y21 for receiving the bottom head of the centerpinthus pro- "'viiding an annularshoulder 22 which cooperates withA said head. y

The center-'pin propercomprises apmain i vbo'dy'portion which is solid and an annuf lar head 23 at the bottom end thereof which cooperates with the shoulder 22 and' is accommodated within the pocket'21 ofthe bolster 11.7" rlhe shank portion 251- adjacent the hea'd'23 is'of such a diameter astorsub- 'stantia'lly fit thegopen'ing 2O of the 'bolster 11) At the'top end, the pin is providedwith a Yset of laterallyA projecting diaine'trically opposite lug-s125725 which are of such ya "siz'e' as'to passV freely through the opening pass" freely through the'pin-receiving open- Y 'L f being vassembled, V,and 'willi pass the linter-V i] rupted'portions of `the-.fiange 18.

As will be evident, when the locking memberis in positionwith the inner sides ofthe arms 1n engagement with the fiat opposite sideportions of the pin, the
